Title: Vacuum cleaner adapter for micro tools
Inventor: SCHNEIDER NORMAN J
IPC: A47L9/24
Filed: 1990-11-15
Abstract: A vacuum cleaner adaptor for micro tools consisting of an adaptor body of tubular form having a large diameter section for fitting to a conventional vacuum cleaner vacuum intake port or positive air pressure discharge port, an integral conical transition section and a small diameter section for fitting to a small diameter hose or tube or to the micro tool per se. In one form, longitudinal slots of arcuate configuration are formed within the conical transition section of the adaptor body at circumferentially spaced positions and are selectively closed off by a rotatable conical form shield having similar sized longitudinal slots therein. Radially projecting members on the shield and adaptor body limit rotation of the shield relative to the body between a full slot open position and a slot partially open position by circumferentially offsetting the slots of the adaptor body and shield. In a further embodiment, oblique holes are formed within the adaptor body large diameter section, oblique to the longitudinal axis of the tubular body. A sector shaped solid shield is rotatably mounted on the body for closing off given oblique holes to reduce air flow through the oblique holes as desired while ensuring sufficient air flow for preventing overheating of the vacuum cleaner motor of air cooled or air passed type.

Patent CA-2052986-A1 (CA)
Inventor: REIME GERD
IPC: H04N5/931
Filed: 1991-10-08
Abstract: In the signal path (1) for the frequency-modulated luminance signal of a video recorder, an equalising circuit (11) is disposed between the video band (2) and the frequency demodulator (3) which, whenever the luminance signals fall below a specific switching level (U16), operates in the mode of a bandpass filter (19) which is tuned to the carrier frequencies of the luminance signals and, whenever the luminance signals exceed this switching level in the direction of higher values, operates in the mode of an amplitude-controlled delay unit. In the latter mode, phase errors caused by recording and transmission are largely cancelled, whereas, in the former mode, oscillation patterns with deteriorated oscillations are again refreshed in terms of amplitude through the resonance effect. The height of switching level (U16) is set by a noise detection circuit (21) which detects the rate of the oscillations which do not pass through a specific detection level of the noise detection circuit situated in the vicinity of the sound point line of the frequency demodulator. The equalising circuit is thereby adapted to the different reproduction quality levels of different video tapes in such a way that image reproduction with minimum interference and maximum definition is achieved. <IMAGE>

Abstract: An  apparatus  for  removing  a  ghost  component which disturbs  a picture  signal  by means  of  a  ghost canceling  reference  signal  included  therein.    The reference signal is extracted from the picture signal and judged  as  to  whether  it  has  a  specific  level  in  a reference time interval.  The extracted reference signal is also judged as to whether a color burst signal is canceled.   If both judgments are positive, a judgement signal is generated which allows the extracted signal to be examined how it is disturbed by the ghost component.          In response to the examination,  the ghost component is removed from the picture signal.
